This invention relates to improvements in display devices and hasparticular reference to a priceindicating' sign, for use indis pensingvarious commodities in measured 5' I V a M quantltles.

' An object of the invention is to provide an improved device of simple,practical, andv be eme inexpensive construction, which ma ployed forindicating current prices of given 10 quantities of a commodity, such asgasoline,-

or the like. Y

Another object is to. adjustably mount a plurality of panels within thecasing off-the device, so that any one of said panels could be 5 movedand secured in a position wherein indicia thereon would be visible to anob server and said indicia read in conjunction with other changeableindicia 011 the-device to determine the price of a certain quantity ofthe commodity being sold.

The above andother objects will appear more clearly from the followingdescription, when taken inconnection. with the aca companying drawing,which illustrates a preferred embodiment of the inventive idea. In thedrawing: V Figure 1 is a front elevation of the device, partially brokenaway, with one of the indicating panels in operative position Figure 2is a fragmentary view similarto. Fig. 1, with all the panels ininoperative posle tion.

Figure 3 is a vertical longitudinal sect-ion through the device, and

Flgure 4 18 a plan new of a dlal used in connection with the device.

The deviceis shown as comprising arectangular frame 5 which is providedwith a front wall 6 that extends from the bottom to a point short of theupper end of the frame, thus'forming an opening 7 in the front of thedevice. I A rear wall 8 projects downwardly from the top of the frame,and its lower end terminates at approximately the level ofthe upper endof the frontwall, said ends slight ly overlapping. Thus the rear of thecasing formed in this manner is left open for a major portion of' itsheight for a purpose which will presently appear.

Mounted in the front wall 6 adjacent'its bottom is a pin 9whichrotatably supports a i dial v10 having a plurality of numbers 11 arranged about its periphery to designate cent denominations, said numbersbeing successlvely exposedthrouglran openmg. 12 soas 5 to be associatedwith a' fixed dollarnumeral' 13"insc ribed on the front wallfi. Oneblank spacello'n the dial 10is provided for registration with theopening 12when the exact cost of the commodity being sold can-bedesignated by. the single numeral 13. Adjustment of the dial 10 may beeffected from the rear of the casing below said rear wall, and in orderto secure said dial in adjusted positions, avvingnut 15' is threadedupon thev pin 9 for engagement with thew a116, so as to bind the dialagainst the washer 16 interposed between said dial'and wall.

Passing through theupper end of the front a wall'6 and the lower end ofthe rear wall 8 is a pin 17 upon which are 'rotatably suspended threepanels 18, 19, and 20, of segmental form andeachhaving a projectingtab21 identified, I

with a different numeral 22, said tabsl pro-1 jecting radially indiiferentfdirections from" i panel may be reached from the rear of theedevice and turned to the desired position. I

Normally,the panels assume a position behind the front wall 6, as shownin Fig, 2-, with only the tabs 21 and the numerals thereof exposed abovethe upper edge of said wall, and they" 7 may be secured in suchinoperatlveposit1on, 3

or either one of them in an adjusted operative position, as shown 1nFigs. 1 and 3, by a wing nut 23 on the pin 17, operating in a manner asimilar to the nut15.

C When usingthe devicefor the saleof gaso- 1 line, for instance, eachpanel has inscribed thereon a numeral indicating the number of,

gallons which may be purchased for the amount designated: by thenumerals '11 and:[ i

inoperative positions; Thus the numeral 69 (Fig. 2 is inscribed on thewall- 8, while the 9 large numerals 7, 87, and 9 Corresponding to thenumerals 22 are placed upon the respective panels 18, 19, and 20,either-Jone of which, when swung to its operative position,

will cover the numeral 6 on the rear point approximately in alignmentwith the; end of said front wall forming an edge of saidopening,,indiciaon said rear wall visible through said opening, a pivotrod'connccting said walls adjacent said openings, a plurality of panelseach mounted for rotary movement on said rod and having indicia thereon,said panels being normally positioned behind said front wall and eachbeing adjustable to a position in alignment with said opening and infront of the indi'cia on said rear wall, and means on said rod forsecuring SitlCl panels in normal and HChHStBCl posltions.

' 2. A display device comprising a casing" consistingjof a frame, afront wall having an opening at its upper end, and another opening belowthe first named opening, a rear wall extending downwardly from the topof said frame and terminating at a' point short of the bottomof saidframe, whereby access may be had to the interior of said casing from therear thereof, a dial. rotatably mounted in back of sai'dfront wall, soas to expose indicia thereon through the second named opening in saidwall, and a'plurahty of panels also rotatably mounted'with'in. SELlClcasing, and

each movable' from' a position'behind said front wall 'to an exposedposition in alignment with said first named opening, said dial andpanels being accessible for rotative adjustment through the open portionof the rear wall of said casing.
